Nonlinear absorption of sound in superconductors
Soviet Journal of Low Temperature Physics, 1976The experimental results are given of investigations of nonlinear effects in the absorption of sound in superconductors. The analysis carried out shows that the data obtained cannot be explained without taking into consideration the concept of increase of the energy gap of the superconductor under the action of high-powered ultrasonic pumping.

Nonlinear refraction and nonlinear absorption of various media
Journal of Optics A: Pure and Applied Optics, 2005A review of studies of the nonlinear refraction and nonlinear absorption of semiconductors, fullerenes, dyes, metals, crystals, and liquids (bulk samples, suspensions, solutions, embedded nanoparticles, and thin films) is presented. Some of these media are analysed as optical limiters of intense laser radiation.

Nonlinear absorption in bifluorene derivatives
SPIE Proceedings, 2004We report here the nonlinear absorption of bifluorene derivatives induced by two-photon absorption (TPA), in order to study the effect of the dimension of the molecule on these properties. Measurements were performed in chloroform between 450 and 650 nm for nanosecond time duration pulses.

Nonlinear Interactions of Light and Matter Without Absorption
2001Nonlinear effects in optics offer the possibility of generating or manipulating light in almost any manner. The laser itself, producing light not available in nature, is the most obvious example. Therefore nonlinear interactions are the basis of photonics.
